BOOT OR SHOE HOLDING JACK.

SPECIFICATION forming part of Letters Patent No. 258,696, dated. May 30,1882.

Application filed April 6, 1882. (No model.)

To all whom it may concern:

Be it known that 1, ELI BERTRAND, of Boston, county of SutTolk, andState of Massachusetts, have invented an Improvementin Boot and ShoeHolding Jacks, of which the following description, in connection withthe accompan yin g drawings, is a specification.

. My invention has for its object the production ofajack to hold a bootor shoe while the edge of an outwardly-turned upper is being stitched ina sewing-machine or otherwise to an outside sole.

In this my invention the last upon which are placed the upper and soleto be united is entered by a last-holding or heel pin extended from astandard or fulcrum block having cooperating with it a lever providedwith a swiveling-block having a toe-rest pivoted upon it, the said blockbeing also provided with a spring-clamp.

Immediately in front of the toe-rest, and adapted to fit the toe of theboot or shoe closely, is a pivoted spring-plate or toe-clamp adapted torock upona leverherein shown as having its fulcra coincident with thepivotofthe toe-rest, the said lever being operated in one direction by aspring, or it may be by a screw. This spring-plate or toe-clamp is freeto move vertically and laterally independently of and with relation tothe toe-rest to readily adapt itself to the particular shape of thelastand the material of the upper about and at the toe of the last, and tohold the toe of the upper firmly in position on the toe of the last whenthe upper and sole are being united.

Figure 1 represents in broken side elevation a sufficient portion of myimproved shoe-holding jack with last and shoe thereon to illustrate mypresentinvention, th e toe-cl am p being, however, omitted, to avoidconfusion of the drawings. Fig. 2 is a detail showing the toeclampapplied as it will be in practice. Fig.3 is a detail of the toe-clamp toshow how it is supported, and Fig. 4 is asectional detail on the line a;at, Fig. 1.

The last a, of usual construction, is fitted upon the heel-pin 1),extended from the standard I), having a backward extension, 11 providedwith a fulcrum-piece, b. The main part of this standard has a slot oropening, I), which receives the lever c, which latter is acted upon bythe end of the screw b, the latter, when moved in the direction of thearrow, forcing the left-hand end of the lever c and its attached partstoward the last and shoe thereon, the right-hand end ofthe said leverresting against the fulcrum b. The lever 0 has connected with it at oneend by pivot 2 a block, (I, to which are attached the spring-clamp and atoe-rest. The spring-clamp is shown as composedof two pieces ofspring-steel d 61 connected with the block (I by a screw, 7. The springd has a piece of leather, 0?, secured within it by rivets 6, the saidleather serving better than metal to insure the requisite amount offriction on the upper about the top of the last to stretch or fit theupper m to the top of the last between its toe and instep as the clampis forced upon or against the upper on the last by the movement of thelever c. The toe-rest e, pivoted upon the lever c at 6 has a concavedface to fit the upper near the toe of the last. To firmly clamp the toeof the upper against the last and guard the upper so that it cannot beinjured by the needle of the sewing-machine or the upper becomeaccidentally moved on the toe of the last during sewing, I have producedthe thin metallic toeclamp f, which is pivoted at 9 upon the link h, inturn pivoted at i on the lever 70, the latter having its fulcrum, asherein shown, on the pin 0 common to the toe-rest. The lever k is actedupon by a spring, k which keeps the acting edge of the toe-clamp andguard f pressed toward and against the toe of the upper, and by reasonof the pivots g t the said toe-clamp is free to rock and to movelaterally with relation to the last, to thus enable the clamp to firmlyhold the toe of the upper and last whether for a right or left 'foot.

By means of the devices shown and described the upper m may be fitted toand held clamped firmly against the last while its outturned edges arebeing stitched to the sole n in a sewing-machine, or by hand-sewing,after which the projecting edges of the upper and sole are trimmed on,making a shoe such as shown in my Patent No. 254,594, the turning of thescrew b or lever-adjustingdevice, as I shall call it, determining theextentof the pressure of the spring'olamp and toe-rest upon the upperand last.

Instead of screw 1), I might employ any other well-known equivalentdevice.

I claim 1. The standard I), tohold the last, combined 5 with the lever0, means to move it, and with the spring-clamp to act upon the upperover the top of the last, as shown, between its toe and instep,substantially as described.

2. Thestandard b", to hold the last, thelever c, :0 and lever-adjustingdevice, combined with the block and toe-rest, substantially asdescribed. 3. The standard to hold the last, the lever, thelever-adjusting .device, and spring-clamp to fit the upper to the last,combined with the toe-clamp, substantially as and for the purpose 1 5described.

4. The lever It and projected toe-clamp, combined with the last,standard I), lever c, and lever-adjusting device, substantially asdescribed.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.
